Hello!
Thank you again for reporting this issue.
We have published a short post explaining the situation in more detail, including a temporary solution you can use while we wait for Gotcha Gotcha Games to update the Steam version:

We have already contacted GGG and reported the problem, so the official correction will depend on them updating the corresponding Steam files.
In the meantime, please follow the instructions in the post, as they should allow you to fix the translation issue manually.
We apologize for the inconvenience, and thank you very much for your patience and understanding!
Best regards, Maxii1996 | Undermax Team
